	* config/i386/i386.md
	(TARGET_SSE_PARTIAL_REG_DEPENDENCY float_extend sf->df peephole2):
	Change to post-epilogue_completed late splitter.  Use sse_reg_operand
	as operand 0 predicate.
	(TARGET_SSE_PARTIAL_REG_DEPENDENCY float_truncate df->sf peephole2):
	Ditto.
	(TARGET_SSE_PARTIAL_REG_DEPENDENCY float {si,di}->{sf,df} peephole2):
	Ditto.  Emit the pattern using RTX.

	(TARGET_USE_VECTOR_FP_CONVERTS float_extend sf->df splitter):
	Use sse_reg_opreand as operand 0 predicate.  Do not use true_regnum in
	the post-reload splitter.  Use lowpart_subreg instead of gen_rtx_REG.
	(TARGET_USE_VECTOR_FP_CONVERTS float_truncate df->sf splitter):
	Ditto.
	(TARGET_USE_VECTOR_CONVERTS float si->{sf,df} splitter): Use
	sse_reg_operand as operand 0 predicate.

	(TARGET_SPLIT_MEM_OPND_FOR_FP_CONVERTS float_extend sf->df peephole2):
	Use sse_reg_opreand as operand 0 predicate.  Use lowpart_subreg
